Robbie Williams has called on his friend Toni Kroos to leave Real Madrid for Manchester United.
The pair share a close relationship, supporting each other in their work as footballer and singer.
"You've won everything in Madrid, I'm asking you to sign for Manchester United!" Williams says in Kroos' documentary.
"I think we have the best league in the world, the Premier League.
"That's why one thing annoys me a lot. Real Madrid have made me feel small, as if I had a small penis.
"Football is my religion and I don't like that there are gods bigger than mine."
